Serial No. 128,277.

My invention relates to mechanisms or machines forwashing and rinsingdishes which are adapted to be assembled and operated in the usualkitchen sink, and the special object of my invention hereinafterdescribed is to provide a removable cover so constructed that whenplaced in position it will allow the faucet levers and soap supply meansto extend above and outside of said cover for convenient manipulationwhile insuring effective prevention of the water-being sprayed on thedishes from escaping in any dii ection outside the limits of the coveror sink.

' ll attain these objects by means of the mechanism which will now hedescribed in detail with reference to the accompanying drawings, whichshow a complete sink dish- Washing machine.

Figure 1 is a front View, sectional through."

the sink and. cover, and Figure 2a cross section view substantially online 2, 2' of Figure 1, showing the preferred construction, with thesoapholder permanently combined with the water outlet fixtures.

Figure 3 is an enlarged View, partly in section, showing the details ofconstruction of the soap container and its by-pass valve, as shown inFigures 1 and 2. Figure 4 is a cross-section view at line 6 of Figure 3,with thesoap container valve turned to shut ofl the flow of waterthrough it.

Similar reference numerals refer to similar parts throughout the severalviews.

The sink 10, which may be of any size 6r type in pse, has the usualoutlet 11 carrying the water oil' to the drain pipes. The sink isprovided with the usual hot and cold water supply pipes 8 and 8'. Thesewater supply pipes are connected up to a single outlet spout 19 by meansof the communicating passage 19, as shown in Figures 1, 2 and 3. Theusual control levers 9 and 9' serve for turning the water on or oil atwill.

The rotary' spray outlet of this machine comprises essentially thehollow globular head to which are secured radial outlet tubes 13 and acentral vertical tube 14. The globular head 15, or itsequivalent,is'permanently connected with the nut 16 by means of a suitable bearing,substantially as is shown by the dotted lines in Figure 3, so that itwill rotate freely on its vertical axis. The nut 16 serves to attachthis rotary spray outlet to-the water spout outlet 19. The radial andvertical tubes 13 and 14 are provided with a number of small openings ornozzles 17 which .areof stich size and number and so located as to causethe water jets to issue therefrom with suflicient velocit the streams sowell distributed 1n direction as to give the most efi'ective results incleaning the dishes. The openings 17 are so located on the radial arms13 that the rev action pressure of the jets therefrom will cause thecontinuous and rapid rotationof the device as long as waterunder pliedto it. v

The dishes to be washed are arranged in a suitable rack 18, preferablyconstructed of wire and circular or rectangular ll'li shape in orderthat {the dishes may be suitably arranged to expose them to the cleaningaction of the sprayed water jets so as to secure the most rapid andeflicient washing. A suitable enclosing cover 32, preferably made ofsheet metal, is essential to confine the sprayed water within the sinkwhen the machine is in operation. A detailed description of this coverwill be given later.

The construction of the soap supply valve and holder is shown clearly inFigures 3 and 4. It consists essentially of a cylindrical cup 20 securedto the top of the by-pass valve 21. This valve.is tapering and isprovided pressure is supwith the direct port 22 and the recessed ports23 and 23, the two latter communicating with the interior of the soapholder 20. A screen wire or perforated partition 24 is located nearitsbottom, and an open inlet tube 25 is provided with its lower endconnecting with the inlet port 23, and extending nearly to the top ofthe soap holder. The screw top 26 allows ready access to the soap holderwhen desired to put soap therein. When the container 20 has beensupplied with soap and the parts are in the position shown in Figure 3with the hot water supply faucet lever and with I open-, hot water willflow. into and through the recessed ports 23 and 23 and the soap holder20, dissolving soap therein and the resulting hot-water suds will flowthrough the outlet spout 19 into the rotary spray outlet, and outthrough the openings 17 and 17' as high velocity jets. The short arrowsindicate clearly this circulation of the water clear hot water will passdirectly through the port 22. Two openings 27 and27" are provided in thewall of the valve seat so that when the valve has been turned to theposition shown in Figure 4 the hot water remainin in the soap holder 20will automatical y be drained oil into the sink through the tubeconnecting with opening 27 air being admitted through the opening 27 toreplace the water. This is quite essential as otherwise the soapremaining in the container would be more or less completely dissolved,resulting in a very rapid and wasteful use of soap. The word Soap on thecontainer 20 is so located that it will face to the front as shown inFigure 1 when the valve is in position to send the entire flow of thewater through said soap holder as shown in Figure 3, thus visiblyindicating when soapy water is being used.

The. removable cover to enclose the dish rack and confine the sprayedwater within the sink when the machine is in operation comprisesessentially a top member 32 with side walls 32 which extend down asuflicient distance below the top of the sink to prevent the escape ofthe sprayed water. An opening 33 in the rear side wall 32, and a similaropening in the top member 32 of the removable cover allows it to bereadily put in place and removed notwithstanding the soap valve 20 andfaucet levers 9 and 9 which should extend through the opening in the topmember 32 convenient for manipulation by the operator. The cover may beof substantially the same oval or rectangular shape as the wire dishrack.

It is very essential that the opening in the top 32 through which thecontrol levers and soap valve extend should be closed so as to preventthe escape of water through it while the machine is in operation. Thesection 35 which is provided for this purpose is permanently secured tothe splash-up back of so that the main removable cover 32 will beaccurately guided into position held suspended from said fixed shelf orlid 35. The clips 36, secured to the front side of the cover may be usedalso as an additional support by resting on the front edge of the sin Itwill be evident that the machine may be provided with a plurality ofdish racks at small additional cost, thereby increasing its capacity perunit of time to any desired extent.

What I claim as my invention is: t

1. .The combination with a sink provided with a back wall, awater-supply conduit and a valve in the conduit, of a spray devicesecured to the conduit, a dish holding rack extending below said device,and a cover to confine the sprayed water within the sink, comprising ahorizontal section permanently secured to the back wall of the sinkbelow the valve and throu h which the conduit extends, and a removaldlesection provided with a recess to fit closely the horizontal section.

2. The combination with a sink provided with a backwall, a water-supplyconduit, and a valve in the conduit, of a spray device socured to theconduit, a dish-holding rack extending below said device, and a cover toconfine the sprayed water within the sink, comprisinga horizontalsection permanently secured to the back wall of the sink below the valveand through which the conduit extends, the said section being providedwith a shoulder at its free edge, and a removable section provided witha recess to fit closely the shouldered portion of the horizontalsection.

the sink by means of'the vertical flange which is (provided withopenings for the pipes 8 an 8' and securely held in the position shownby the usual flanges and fittings thus forming a secure andpermanentshelf below the faucets and soap valve. Its edges are recessed at thefront and side-as clearly shown in Figures 1, 2 and 3, thus forming aledge 34 corresponding in sha e and size with the opemng inthe top mere1' 32 of the cover.
